Zev Color Coded Recoil Springs Blue 12 Pound

High quality round wire recoil springs are color coded for easy identification. No more counting coils or guessing if you have the correct spring. Red spring is 14 pounds and is ideal for hot 9mm, .40 S&W or .45 ACP. Blue spring is 12 pounds and ideal for standard velocity 9mm. Green spring is 16 pounds. Coating on the spring will typically last 3000 cycles which is our recommended life of the spring. ZEV recoil springs will work in captured and uncaptured guide rods. When using a captured guiderod you will also need the ZEV spring retaining washer. More spring weights coming soon.
